Verbena plant named ‘USBENAS26’

ABSTRACT

A new and distinct cultivar of  Verbena  plant named ‘USBENAS26’, characterized by its low and outwardly spreading plant habit; vigorous growth habit; numerous large light purple-colored flowers; and tolerance to Powdery Mildew.

Botanical designation: Verbena hybrida.

Cultivar denomination: ‘USBENAS26’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Verbena plant, botanically known as Verbena hybrida, and hereinafter referred to by the name ‘USBENAS26’.

The new Verbena is a product of a planned breeding program conducted by the Inventor in Hikone, Shiga, Japan. The objective of the breeding program is to develop new disease-resistant and high temperature-tolerant Verbena cultivars with semi-upright plant habit and attractive flower coloration.

The new Verbena originated from a cross-pollination made by the Inventor on May 25, 1999 of an unnamed selection of Verbena hybrida, not patented, as the female, or seed, parent with a proprietary selection of Verbena hybrida identified as code number VJS9-2, not patented, as the male, or pollen, parent. The cultivar USBENAS26 was discovered and selected by the Inventor as a flowering plant within the progeny from the aforementioned cross-pollination in a controlled environment in Bonsall, Calif. on Jun. 10, 2000.

Asexual reproduction of the new cultivar by cuttings at Bonsall, Calif., since Jul. 1, 2000, has shown that the unique features of this new Verbena are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘USBENAS26’. These characteristics in combination distinguish ‘USBENAS26’ as a new and distinct cultivar:

-   -   1. Low and outwardly spreading plant habit.     -   2. Vigorous growth habit.     -   3. Numerous large light purple-colored flowers.     -   4. Tolerant to Powdery Mildew.

In side-by-side comparisons conducted in Hikone, Shiga, Japan, plants of the new Verbena differed from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Verbena were more vigorous than plants of         the female parent selection.     -   2. Plants of the new Verbena had larger flowers than plants of         the female parent selection.     -   3. Plants of the new Verbena flowered earlier than plants of the         female parent selection.

In side-by-side comparisons conducted in Hikone, Shiga, Japan, plants of the new Verbena differed from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Verbena were more upright than plants of         the male parent selection.     -   2. Plants of the new Verbena flowered earlier than plants of the         male parent selection.

The new Verbena can be compared to the cultivar, Sunmaref TP-P, disclosed in U.S. Plant Pat. No. 9,014. However, in side-by-side comparisons conducted in Bonsall, Calif., plants of the new Verbena differed from plants of the cultivar Sunmaref TP-P in the following characteristics:

-   -   1. Plants of the new Verbena were more upright than plants of         the cultivar Sunmaref TP-P.     -   2. Plants of the new Verbena had taller inflorescences than         plants of the cultivar Sunmaref TP-P.     -   3. Plants of the new Verbena flowered earlier than plants of the         cultivar Sunmaref TP-P.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants grown in 15-cm containers were used for the aforementioned photographs and following description. Plants had been growing for about twelve weeks when the photographs and the description were taken. Plants were grown under conditions which closely approximate commercial production conditions during the summer in Bonsall, Calif. in an outdoor nursery. During the production period, day temperatures ranged from about 18 to about 35° C. and night temperatures ranged from about 10 to about 21° C.
